I hadn't really intended to write this, I'd been interested in the backstory but I didn't really have a strong fix on it, and then I was looking at some of the info screens we get in Episode Gladio and I realized it would be really interesting if Cor was like a 'wrong side of town' type of kid, that would explain why he joined so early, etc. He's so serious in game it's hard to imagine him as a hotheaded kid, so I took all that and it sort of flowed well enough.

It also gave me an excuse to work out the '30 years ago' timeline which had been bugging me for a while, so it was a win-win.
